Mike,
Every now and then Model Expo has some vintage racing cars, usually Grand Prix racers from the late 40's thru the very early 60's.
Some are cast metal bodies and plastic parts, these are expensive!
Then, there are the same kits with the body panels in plastic, these are really nice and inexpensive. I bought the 1956 Ferrari for $29. It is in 1/20 scale, same as the rest of my F1 kits.
If this interests you, I'll post the URL.

I know it's only rock and roll, but I like it.
